Install ReactJS and Environment Setup

A development environment is a collection of tools, software, and hardware used by software developers to construct software applications. It comprises a text editor, a version control system, testing tools, and other software development tools. A development environment is important because it enables developers to write, test, and deploy software applications more efficiently and effectively.

Because ReactJS is a JavaScript library, it necessitates the establishment of a development environment in order to develop and run apps. To develop and run code, ReactJS uses Node.js, NPM, and a text editor. Git and GitHub Desktop are also required for version control and collaboration.

Without setting up a proper development environment, developers may face challenges in creating and testing their applications, leading to longer development times and potentially buggy software.

Therefore, setting up a development environment for ReactJS is crucial for developers to create high-quality applications.

Install Node.js and NPM

Here's a step-by-step guide on how to install Node.js:

  1. Go to the official Node.js website: ****
  2. Choose from the "LTS" OR “Current” button on the homepage.
  3. Select the appropriate version of Node.js for your operating system. There are versions available for Windows, macOS, and Linux.
  4. Run the downloaded installer.
  5. Follow the prompts in the installer. You may need to agree to the license terms and select the installation location.
  6. Select the components you want to install. The default options should be sufficient for most users and click on next unless the below screen comes.
  7. Click the "Install" button to begin the installation.
  8. Once the installation is complete, you can verify that Node.js is installed by opening a command prompt (Windows) or terminal (macOS, Linux) and typing "node -v" (without quotes). This should print the version number of Node.js installed on your system.
  9. That's it! You've successfully installed Node.js on your computer.

Installing NPM

To install NPM(Node Package Manager), you will need to first install Node.js, which includes NPM as a default package.

Here are the steps to install NPM on a Windows, Mac, or Linux operating system:

  1. Once Node.js is installed, open your terminal or command prompt.
  2. To check if Node.js and NPM are installed correctly, type **node -v** and **npm -v** respectively in the terminal. It should display the version of Node.js and NPM because NPM comes with node.js and gets installed while installing node.js.
  3. If NPM is not installed or is outdated, you can install it separately or update it by running the command **npm install -g npm** in the terminal. This will update NPM to the latest version.
  4. To verify the NPM installation, type **npm -v** in the terminal. It should display the latest version of NPM.

That's it! Now you have successfully installed NPM on your system. You can use NPM to install and manage packages for your Node.js projects.

Code Editors

????✏️ Code editors are software applications designed to write and edit source code for software development. They are essential tools for developers and programmers, providing features such as syntax highlighting, auto-completion, debugging, and collaboration.

????‍???? There are many code editors available, ranging from simple text editors to feature-rich Integrated Development Environments (IDEs). Some popular code editors used for ReactJS development include Visual Studio Code, Sublime Text, Atom, and WebStorm.

???? Install anyone of your choice and we will be doing our coding and development process on the editor which provides many functionalities to make our tasks easier and faster.


A development environment is an important part of ReactJS development since it provides the required tools, software, and hardware to efficiently and successfully design, test, and deploy software applications. To build applications, ReactJS uses Node.js, NPM, a text editor, Git, and GitHub Desktop, among other things. A well-configured development environment can help developers boost productivity, optimise their workflow, and produce higher-quality code.
